A 100 kg cart accelerates from 0 to 20 m/s in 5 seconds. What is the acceleration?
the mass does not matter.
a = (20m/s)/(5s) = (20/5) m/s^2
To find the acceleration, we can use the formula:
acceleration = change in velocity / time
Given that the initial velocity (u) is 0 m/s, the final velocity (v) is 20 m/s, and the time (t) is 5 seconds, we can substitute these values into the formula:
acceleration = (v - u) / t
acceleration = (20 - 0) / 5
acceleration = 20 / 5
acceleration = 4 m/s^2
Therefore, the acceleration of the cart is 4 m/s^2.
